Troubled star Britney Spears' former manager Larry Rudolph has refuted reports the singer is in secret negotiations to stage a major comeback spectacular in Las Vegas.

Rumors of a Sin City performance emerged earlier this month, after the pop star was spotted dining with Palms Hotel & Casino owner George Maloof Jr. in Los Angeles.

But Rudolph has denied claims the "Toxic" hitmaker will be appearing on stage in the Nevada city.

He tells the Las Vegas Review Journal, "She's not here (in Las Vegas) and she's not coming in. I wouldn't lie to you."
